Turn an unknown scope into a decision-ready inventory.
Start with one business service or agreed asset scope. Identify cryptographic use, confidentiality needs, and vendor dependencies.

Phased migration roadmap
AcceptanceEach asset has a traceable source, owner, and status. Uncovered areas remain explicit.
Architecture & pilot · Validate a complete path in a controlled environment.
Compare architecture options for a connection or signing use case. Define product support, tests, acceptance criteria, and rollback.
Architecture options, trade-offs, and test matrix
Compatibility and performance comparison
Negotiation or signature test evidence
Failure, fallback, and recovery exercises
AcceptanceUse agreed performance and compatibility criteria, with repeatable success and failure tests.
Migration governance · Give every migration batch a reviewable basis.
Use pilot evidence to plan migration batches and review changes, while maintaining assets, dependencies, and exceptions.
Rollout plan and responsibility matrix
Change review and validation criteria
Procurement requirements and exceptions
Vendor updates and periodic review
AcceptanceRecommendations trace back to evidence. The customer owns approval and cutover, with open items and owners recorded.
Advisory covers analysis, design, and evidence review. Authorized customer teams and vendors execute production changes; implementation, licenses, and support require an agreed scope.
03 / A FOCUSED PILOT
One scenario. Testable evidence.
Validate the complete connection path.
Check client, proxy, and server versions before evaluating suitable PQC or hybrid key establishment.
What to measure
Negotiation, handshake latency, connection success, and fallback behavior.
Scope consideration
Verify key establishment and certificate signatures separately. Edge support does not establish end-to-end protection.
Websites & APIs · Validate the complete connection path.
Check client, proxy, and server versions before evaluating suitable PQC or hybrid key establishment.
What to measure
Negotiation, handshake latency, connection success, and fallback behavior.
Scope consideration
Verify key establishment and certificate signatures separately. Edge support does not establish end-to-end protection.
Software & document signing · Check signing and verification at every endpoint.
Map signing, verification, and update dependencies, and confirm ML-DSA or SLH-DSA support in specific products.
What to measure
Signature and key size, verification performance, trust chains, and legacy compatibility.
Scope consideration
Long-term validation also depends on certificates, timestamps, and preserved evidence.
Devices & vendor dependencies · Align vendor roadmaps with your plan.
Inventory device, PKI, HSM, and library versions and lifecycles. Confirm implementation scope and upgrade paths.
What to measure
Available versions, protocols, validation scope, licensing, and maintenance cycles.
Scope consideration
A PQC announcement does not confirm support for your model, version, and configuration.
04 / YOUR NEXT MOVE
Find your starting point.
Answer three questions to prepare a scope for your next internal discussion.
No contact details required. Answers are processed on this page and are not submitted by this questionnaire.
Begin with inventory, prioritization, and vendor checks. Stage replacements with compatibility, performance, and rollback validation.
Does enabling PQC on a website complete the migration?
Check edge-to-origin traffic, internal services, key management, and signing separately. PQC key establishment does not imply migrated certificate signatures.
Does using a NIST algorithm mean certification?
Algorithm standards, implementation correctness, and cryptographic module validation are separate. Check the product, version, and validation scope.
How does PQC differ from steganography and QKD?
PQC uses algorithms on conventional computers to resist known quantum attacks. Steganography hides the presence of information; QKD requires quantum channels and equipment. This service focuses on PQC migration.
How are costs and timelines confirmed?
Confirm assets, applications, test environments, and vendor support, then agree the assessment, pilot, migration, and support scope.
